The existing `acme.TLSALPN01` challenge class did not have
a `response_cls`, meaning it was not possible to use a tls-alpn-01
challenge with `client.answer_challenge`.
To support the above a simple `TLSALPN01Response` class is added that
doesn't provide the ability to solve a tls-alpn-01 challenge end to end
(e.g. generating and serving the correct response certificate) but that
does allow the challenge to be initiated. This is sufficient for users
that have set up the challenge response independent of the `acme`
module code.
Resolves#6676
This PR passes the CERTBOT_NO_PIN environment variable to the unit tests tox envs. By setting CERTBOT_NO_PIN to 1 before executing a given tox env, certbot dependencies will be installed at their latest version instead of the usual pinned version.
I also moved the unpin logic one layer below to allow it to be used potentially more widely, and avoid unnecessary merging constraints operation in this case.
As warnings are errors now, latest versions of Python will break now the tests, because collections launch a warning when some classes are imported from collections instead of collections.abc. Certbot code is patched, and warning is ignored for now, because a lot of third party libraries still depend on this behavior.
* Allow to execute a tox target without pinned dependencies
* Correct lint
* Retrigger build.
* Remove debug code
* Added test against unpinned dependencies from test-everything-unpinned-dependencies branch
* Remove duplicated assertion to pass TRAVIS and APPVEYOR in default tox environment.
I observed that the current set of oldest requirements do not correspond to any environment, except the specific Xenial image in Travis CI (and standard Xenial containers will also fail).
It is because the requirements make cryptography and requests fail against standard libraries available in the typical Linux distributions that are targeted by the oldest requirements approach (Centos 6, Centos 7, Xenial, Jessie).
This PR fixes that, by aligning the minimal version requirements of cryptography and requests to the maximal versions that are available on Centos 6. Centos 7, Jessie and Xenial stay unusable with oldest requirements for other reasons, but at least one old and supported Linux distribution is able to run the tests with oldest requirements out of the box.
A test is also corrected to match the expected error message that old versions of urllib3 will raise.
Fixes the problem at https://github.com/certbot/certbot/pull/6592#discussion_r245106383.
The tests use `eval` which neither myself or `pylint` like very much. I started to change this by splitting the path we wanted to test and repeatedly calling `getattr`, but it didn't seem worth the effort to me.
* Add missing acme.jose attribute.
* update changelog
When working on an update to our packages in Ubuntu Xenial, @NCommander noticed that importing code through acme.jose no longer works since josepy became a separate package and remembers having to fix up some code that was using acme.jose himself.
This PR should fix that problem by making all of josepy accessible through acme.jose. This is primarily beneficial to our OS package maintainers who want to avoid subtle API changes when updating packages in stable repositories. They will likely backport this change, but I figure we might as well add it ourselves to minimize divergences in our OS packages in the future and avoid problems on the off chance someone hasn't upgraded acme and was relying on this feature.

So here we are: after #6361 has been merged, time is to provide an environment to execute the automated testing on Windows.
Here are the assertions used to build the CI on Windows:
every test running on Linux should ultimately be runnable on Windows, in a cross-platform compatible manner (there is one or two exception, when a test does not have any meaning for Windows),
currently some tests are not runnable on Windows: theses tests are ignored by default when the environment is Windows using a custom decorator: @broken_on_windows,
test environment should have functionalities similar to Travis, in particular an execution test matrix against various versions of Python and Windows,
so test execution is done through AppVeyor, as it supports the requirements: it add a CI step along Travis and Codecov for each PR, all of this ensuring that Certbot is entirely functional on both Linux and Windows,
code in tests can be changed, but code in Certbot should be changed as little as possible, to avoid regression risks.
So far in this PR, I focused on the tests on Certbot core and ACME library. Concerning the plugins, it will be done later, for plugins which have an interest on Windows. Test are executed against Python 3.4, 3.5, 3.6 and 3.7, for Windows Server 2012 R2 and Windows Server 2016.
I succeeded at making 258/259 of acme tests to work, and 828/868 of certbot core tests to work. Most of the errors where not because of Certbot itself, but because of how the tests are written. After redesigning some test utilitaries, and things like file path handling, or CRLF/LF, a lot of the errors vanished.
I needed also to ignore a lot of IO errors typically occurring when a tearDown test process tries to delete a file before it has been closed: this kind of behavior is acceptable for Linux, but not for Windows. As a consequence, and until the tearDown process is improved, a lot of temporary files are not cleared on Windows after a test campaign.
Remaining broken tests requires a more subtile approach to solve the errors, I will correct them progressively in future PR.
Last words about tox. I did not used the existing tox.ini for now. It is just to far from what is supported on Windows: lot of bash scripts that should be rewritten completely, and that contain test logic not ready/relevant for Windows (plugin tests, Docker compilation/test, GNU distribution versatility handling and so on). So I use an independent file tox-win.ini for now, with the goal to merge it ultimately with the existing logic.
